Abstract :
A bandgap reference generator with a compensation circuit against temperature variation is presented. The bandgap reference generator provides a reference current of 10μA with temperature coefficient (TC) of only 4.36ppm/°C under temperature range from -40 to 125°C. The chip is fabricated in a 0.18-μm standard CMOS process with a 1.8V power supply voltage, and the active die area is 0.008mm2.
